A. H. BODGE May 18, 1965 REELS Original Filed July 2l, 1958 MM Mme/MUnited States Patent O 1958. This appiication Feb. 1, 1963, Ser. No.255,545 3 Claims. (Cl. 242--7 4) This application is a continuation ofmy original application Serial No. 749,749, filed Iuly 2l, 1958, nowabandoned.

This invention relates to reels and has for its object certainimprovements in the construction of reels. The invention relates moreparticularly to reels of the type used to wind and unwind relativelylong lengths of tape, film, ribbon and the like.

The conventional reel comprises a pair of opposed and spaced side angessecured to a hub centrally disposed between the two flanges. The tape iswound on and unwound from the hub between the -flanges. Investigators inthis art have proposed numerous forms of reel construction to overcomecertain problems. Among those problems is one having to do with thefastening of the starting end of the tape on the reel lfor the lwindingoperation so that the remainder of the tape may be wound lfairly tightlyon the reel without slippage of the tape. At the same time it is desiredthat when the tape is unwound lfrom the reel, the starting end lmay 'oefreely and easily released Ifrom the reel -without damage to the tape,or indeed to the reel. To this end various forms of slots, for example,in the hubs have been suggested and used.

Another problem has to do with the ease of fastening the starting end ofthe tape to the reel. It is desired that an operator may perform the actof fastening the starting end of the tape in a relatively simple andquick manner. To this end the slots have Ibeen Varied in size and shapeand location.

As a result of my investigations I have discovered certain improvementsin the construction of reels that go far to solve problems of the kindmentioned.

These and other objects of the invention will be more readily understoodby referring to the accompanying drawing, taken in conjunction with thefollowing description, in which FIG. 1 is a plan View of a reeldiagrammatically illus trating a practice of the invention, showing theouter face of a flange provided with a new form of slot to receive thefastening end of the tape;

FIG. 2 is an enlarged fragmentary inside view of the -spaced pear-shapedopenings or windows 14, 16, 18 and 29. These openings terminate at theirinward portions With a composite cylindrical hub 22. A curved or arcuateICC tape threading slot -24 etxends across the liange through thecomposite hub into and through the hollow interior of the hub fromwindow 14 to window 16. The slot thus cuts through the hub at two spacedplaces. The outer edges of the slot in flange 12 are beveled tofacilitate insertion of the tape (FIGS. l and 4). A piece of tape 3G isshown threaded in the slot. To accomplish this, the free end of the tapeto :be fastened to the reel is lfed between the flanges in the customarymanner. It is then grasped by the lingers of the operator through Window16, for example, pulled outwardly, pushed sidewise into the slot, -withits extreme end 32 protruding a short distance from the slot throughWindow 14, as shown. The reel may then he rotated anti-clockwise, as onelooks at FiG. 1, in the direction indicated by arrow 63. Free end 32extends outwardly from the hub, thus providing a small portion of tapethat can be ybent to the right, as one views FiG. 1, toward and inengagement with the hub. As the reel rotates, the first wound layer oftape 30 bears the lfree end 32 downwardly onto the hub and fastens itsecurely into position, thus preventing slippage of the tape on the huband hence in the reel.

Still referring to FIG. l, it will be noted that liange 12 and spacedwindows 14, 16, 18 and 2t) form what may be referred to conveniently asspokes, or spoke portions, 34, 36, 313 and itl of flange 12 extendingtherebetween. The latter three spokes form a rigid integral part of theiiange. Spoke 34, between spaced open windows l14 and 16, however,terminates at slot 24. With the reel in its unassembled condition, theportion of the spoke next to the slot is quite free and flexible; which,however, is not the case when the reel is assembled, as will appearbelow. The bottoms of open windows 14 and 16 and the bottom of spokeportion 34 are formed of a succession of rim sections to be describedbelow.l

The central portion of flange 12` is provided in its axial center withthe usual spindle hole 42 with spaced lateral keyways. Also in thecentral portion of the flange, inside the area defined by composite hub22, is a plurality of coutersunk drive-pinholes 44, 46 and 4S. One ormore of them are adapted to engage with one or more drivepins on a tapetransport found on recorders.

A-s shown in FIG. 2, a similar curved or arcuate slot Sti extends.between the windows 53 and 6i) of the second flange, opposed to Windows1S and 2t! in the first flange 12. That construction is described belowin more detail. The outer edges of the slot are beveled (FIG` 4) tofacilitate insertion of the tape.

FIGS. 2, 3 and 4 show the construction of hub 22. It is a composite oftwo interlocking or telescoping hubs, as will now be described. Piange12 (FIGS. 1, 3 and 4) has its opposed and complementary liange 52 (FIGS.2 and 4). They may .be regarded for convenience as female flange 12. andmale :flange 52.

Going to FIG. 2, it shows the second or male lflange 52 in an enlargedfragmentary view. Spaced Windows 54, 56, 5S and et? are shown partially.They have their complementary eounterpafrtslGFIG. 1) in windows :14,'16, 1S and 20 in the first or female flange '12. As -just indicatedcomposite hub 22 (IFIG. 1) is integrally formed of a pair of telescopinghubs (FIG. 4). FIG. -2 yalso shows spokes, or spoke portions, 64, 65,63, and id of ange 52 extending between the windows. They have theircomplementary counterparts in spokes Eil-t, 36, .3S and 4i? except Pthat spoke 64 has a loose end at slot Se (actually where slot 50 is tobe located, so far as FIG. 2 is concerned), whereas Spokes 66, 68 and7l) form a rigid integral part of their flange 52. This is because slots24 and 50 (FIG. 1) not only are on reverse sides of the reel but are inopposed directions to each other. As indicated composite hub 22 isformed in part of a male cylindrical hub 7;2 integral-ly secured to itsllange. As shown in FIG. 2, this latter lnrb is in turn formed of Wallsections, going in a counterclockwise direction, 74, 76, 78, 80, 82,814, 'S6 land 88; the sections in turn -being divided by spaces 92, 914,96, 98, 100, 102, 1104 and :106, respectively. Spaces or slits 9'4la-nd110'6 become va part of curved slot 50 .and spaces or slits v 98and l102 become a part of curved slot 24 when the hubs are telescopedinto eac-l1 other (FIG. 4). -The other free spaces are adapted toaccommodate complementary -portion-s of the female hub. The peripheraledges of the male hub sections .are beveled, as shown. This is tofacilitate telescoping of the male and yfemale hubs. The hub sectionsare provided inwardly with reenforcing ribs 108 to give them addedlateral strength.

Still refenring to FlG. 2, curved slot 24 ext-ends through male ilange512. However, more is to be said about its formation. A curved orarcuate tape guiding inner (closest to the yaxial center of the reel)wall 1112 integrally secured to the inner side of Vthe flange -extendsalong'the inner side of the arc, including a portion of pinhole 48,

vthe extreme lateral ends of the wall being integrally secured to Wal-lsections 78 and '88 of mal-e hub .i5-2, the outer or freeY portions ofthe are wall having beveled edges, as shown. The arc wall .is provid-ed'with reen-forcing ribs,

as shown, to give added lateral strength. As will be evi- Ident ibelow,this arc Wall complements another arc Wall in the female portion of thereel to give the desired slot ;Now, going to slot 24, FIG. 2 shows acooperating 'curved or arcuate tape guiding outer (-farthest from the.axial center of the reel) wall 116 integrally secured to the 'inneryside of male llange 512, the free edges of the wall Ibeing beveled, asshown. The arc wall extends around a portion of pinhole 44. The extreme'lateral ends of the arc-lwall are integrally secured to sections 82 and8'4 of male hub 52. I The wall is provided with reenforcing ribs,

Ylas before.

The reel shown, particularly in FIGS. 2, 3 and `4, is provided withspecial means -for aligning or orienting the 'male and female hubs, andhence ilanges 12 and I52, and

dor preventing lateral displacement between the two. Thus the maleportion of the reel, FIG. Q, is provide-d with a boss 120 integrallysecured to the inner side of hub secltion 74 Iand the inner side ofllange 52; the boss in turn having .a hole |122 to receive acomplementary .telescoping pin from the female il-ange. 'T he bossincludes a lateral- -lly extending reenforcing wall 1214. As part of thealign-l ing means, FIG. 2 also shows `a telescoping or orienting pin 126adapted to lfit in a complementary hole in :a boss, such .as ju-stdescribed, extending from the inner side of the female llange.

. Spindle hole 42 is described above in connection with FIG. 1. iIt .isalso shown in FIG. 2. A raised circular portion 130 of the inner side ofmale llange 52V is re- Venforced lwith, outwardly extending hub portions132, 134

The parts of that shown in FIG. l. FIG. 3 is quite Vsimilar to FIG.

male hub 14) Iis also divided into a plurali-ty of wa-ll sections,counterclockwise, I142, 144, 146 `and 148; the same being separated fromeach other by spaces 152, 154, 1'56 ,and 158, respectively. Spaces 154and .156 help to form -slot `24 While spaces 152 and |158 help to formtape threading slot 5o. The hub sections are provided inwardly with aplurality of reenforcing ribs 160 to give them added latera-1 strength.

Still referring to FIG. 3, slot 24 extends through female lfla-nge -i12.A curved or arcuate tape guiding (closest to the axial center of thereel) wall 16-2 integrally secured to the inner side of the llangeextends .along the inner side of the arc, including a portion of pinhole414, the extreme lateral ends of the IWall being integrally secured towall sections 144 :and \148 of female hub 140. The outer or freeportions of the :arc walls have bevelededges, las shown. The arc wall isprovided with reenforcing ribs, as shown, to give added strength. VThisarc wall complements arc wall 1116 in the male portion of the reel togive .the desired slot 24.

Now, going to slot 50, FIG. 3 shows a cooperating curved or arcuate tapegui-ding outer (farthest fromthe axial center of the reel) wall -166intgerally secured to the inner side of th-e fia-nge, the free edges ofthe wall being beveled as shown. The arc Wall extends around :a portionof pinhole 48. VThe extreme lateral ends of the arc wall are integrallysecured to wall section =142 of female hub V140. The wall is providedwith reentorcing ribs, as before. Y

AAs indicated above,land as shown particularly in FIGS. 2, 3 and 4, thereel is provided with :special means for aligning the male a-nd fem-alehubs and for preventing lateral displacement between the two. The partsfor the two complement each other, as will be shown. Thus, thefemalepo'rtion of the reel (FIG. 3) is provided with a boss 168integrally secured to the inner side of hub section 146 :and the innerside of llange 12; Ythe :bossin turn having ya hole .17 (lV to receive acomplementary telescoping or orienting pin .126 (FIG. 2) from the malellange. The boss includes ,a laterally-extending reentorcing wall r172.As part of the aligning means, FIG. 3 also shows -a telescopin-g pin11716 adapted to .fit in its complementary hole 122 inboss 120 (FIG.2).V

Spindle hole 42 is described above in connection with FIGS. 1 and 2; Itis also shown in FIG. 3 in a raised circular portion 180 of the innerside of female flange 12, reinforced with inwardly extending hubportions 182, 184 and 186. They are the counterpart of similar hubportions 132, 134 and 136 (FIG.Y 2), on the inner side of the maleflange. The parts just referred to, as indicated above, may beconsidered as part of an inner hub specially provided for the spindlewhen in use, for example, on a Yrecording machine.

The two halves of the reel, constituting the male and female portions,may be made of any suitable material. Plastics have practically replacedmetals. It is preferred to use a suitable plastic, such as styrene,because the two 2 except generally that cylindrical female hub 140 has aslightly-larger:diameter than male hub 72 so that thejtwo may betelescoped into one another quite readily.V Fehalves lend themselvesreadily 'to being separatelyV moulded. Once they have been moulded, theyare fitted or telescoped into each other to form an integral unit. Tothis end, a suitable solvent or adhesive, for the particular plasticemployed, is placed on Vthe male Vor female, or. both, hub surfaces thatare to be brought into sliding contact witheach other. Y

Curved wall 162;(FIG. 3) of the female half is brought, for example, ina generally juxtaposed position to wall 116 (FIG. 2) of the male half.This bringspinholes 44 ofeach half in alignment with each other. At thesame Vtime .curved wall1r12 (FIG. 2) isV brought in a generallyjuxtaposed position to wall 166:(FIG'. 3), thus Vbringing pinholes 48 ofeach half in alignment with each other.

As shown in the-drawing, the bottoms of spaced open Windows 14 and 16and the bottom of spoke portion 34 of p Aflange 11.2V therebetween areformed of a succession of sections 148, 146 Vand 144 of the rim `portionofthe hub 22,

the sections being separated by tape threading slot 24 at the bottoms ofthe open windows 14 and 16; and the bottoms of spaced open windows 58and 60 and the bottom of the spoke portion 64 are formed of a successionof sections 144, 142 and 148 of the rim portion of the hub 22, thesections being separated by tape threading slot 50 at the bottoms of theopen windows 58 and 60.

Aligning pin 176 (FIG. 3) is inserted in aligning hole 122 (FIG. 2),while aligning pin 126 (FIG. 2) is inserted in aligning hole 170 (FIG.3). Furthermore, reenforcng shoulders 169 (FIG. 3) of female hub 140 litinto spaces 92, 96, 100 and 104 in male hub 72. This brings the centralportions of the two halves into a position, such as shown by FIG. 4.Once the solvent or adhesive action goes to completion, the two halvesare held in a permanent unitary whole reel, and spokes 34 and 64 are nolonger loose.

Curved or arcuate slots 24 and 50 depend from cornposite hub 22 aconvenient distance. They should, of course, be clear of the spindle andits associated parts. While arcuate slots are shown, they could, ofcourse, be sinuous, for example, or any other desired shape. The arcuateslot has the advantage of simplicity, which also facilitates themoulding operation referred to.

Returning to slot 24, it may be regarded as an open sided channeldefined by three side walls: the inner side of male flange 52 (FIG. 2),outer tape guide wall 116 (FIGS. 2 and 4) and inner tape guide wall 162(FIGS. 3 and 4). The open side is, of course, in female flange 12. Slot56 may be regarded, similarly, as an open sided channel defined by threeside walls: the inner side of female ange 12 (FIGS. l and 4), inner tapeguide wall 112 (F1GS.2 and 4) and outer tape guide wall166 (FIGS. 3 and4). The open side is, of course, in male ange 52. Both slots or channelsmay be regarded as being formed wholly in composite hub 22, the hubitself providing two open spaces communicating with the extreme openends of the slots. The reel may be mounted on a spindle with eitherflange on top` Thus slot 24 or slot 50 may be made available to theoperator. One at a time is enough. Furthermore, the type of slot hereindisclosed makes it Very easy for the operator to thread the tape on thereel.

It is possible today to mould the parts with extreme precision. Theilanges may be quite thin, as may the male and female hubs; as a resultof which the composite hub of the assembled reel is itself quite thin.The latter is more than strong enough, however, to hold the tape and towithstand its winding and unwinding during use of the reel.

It will be appreciated by those skilled in this art that the above is byway of illustrating a practice of the invention, and that the inventionlends itself to some useful modifications.
